SPRING CONSTRUCTION.

Specification of Letters Patent.

Patented Feb. 12, 19118.

Application filed April 28, 1917. Serial No. 165,178.

To all whom it may concern:

Be it known that I, JOHN WELsBY GELL- ING, a British, subject, residingat the city of Mexico, Mexico, have invented certain new and usefulImprovements in Spring Constructions, of which the following is aspecification.

This invention relates to certain new and useful improvements in springconstruction.

The primary object of the invention is the provision of a springadaptable for various uses and arranged whereby a great amount ofresiliency is obtained.

A further object is the provision of a spring structure includingcooperating leaf and corrugated spring elements.

In the drawings forming a part of this application and in which likedesignating characters refer to corresponding parts throughout theseveral views:-

Figure 1 is a longitudinal sectional view of a form of the device formedof a rectangular metallic strip with a thickened central portion.

Fig. 2 is a plan view thereof.

Fig. 3 is a view similar to Fig. 1 with the spring formed of a doubletapered metallic strip.

Fig. his a plan view of the same.

Fig. 5 is a view similar to Fig. 1 with the spring formed of arectangular metallic strip of equal thickness throughout.

Fig. 6 is a plan view thereof.

Fig. 7 is a plan view of a spring formed of a metallic strip havingthickened endsand one arcuate side.

Fig. 8 is a longitudinal sectional view I taken upon line VIII--VIII ofFi 7 Fig. 9 is a side view of a dou le leaf spring employing two of themembers illustrated in Figs. 5 and 6.

Fig. 10 is a top plan .view thereof.

Fig. 11 is a transverse sectional view taken upon line XI-XLof Fig. 12of a triple leaf spring.

Fig. 12 is a top plan View of the same.

Fig. 13 is a side view of a double leaf spring employing the membersthereof in flat arrangement.

Fi 14 is a sectional view taken XI --XIV of Fig. 13.

The invention broadly consists in the formation of an advantageousspring structure especially serviceable as a vehicle spring upon lineformed in slightly different manners, each embodying substantially thesame principles, a reslhent metallic strip being arranged incorrugations for accomplishing the desired effect and arranged eithervertically, horizontally or at intermediate angles in the formation ofthe complete device which is formed of one or more alternate or combinedflat and corrugated spring members, the latter having lateral, vertical,torsional and reciprocal or longitudinal resiliency and arranged withguide and positioning plates or leaves restricting the movement thereofwithin the desirable limits.

A resilient metallic strip 10 having parallel edges and tapered inthickness from the central portion 11 to the opposite ends 12 thereof isarranged in waves or corrugations producing the spring formationillustrated in Figs. 1 and 2 of the drawings while a similar strip 13having opposite convex arcuate sides 14 may be similarly corrugatedforming the spring structure illustrated in Figs. 3 and 4.

A metallic strip 15 similar to the strip 10 may be employed havinguniform thickness and bent into a plurality of regular loops 16producing a spring as illustrated in Figs. 5 and 6 While a strip 17similar thereto but with a single curved or arcuate side 18 may belooped, as illustrated in Figs. 7 and 8 with the largest loop 19 at thecenter thereof and loops gradually decreasing in length toward theopposite ends 20 of the spring, which ends are preferably thickened forimparting the additional strength in mounting the spring, receivingperforations 21 being arranged through said ends.

A double leaf spring may be formed of two of the spring members 15forming leaves with the corrugations horizontally and transverselythereof, plates or plain leaf springs 22 being arranged between whichthe corrugated leaves 15 are positioned and secured in any desiredmanner, one of the said plates 22 having terminal attaching beads orrolled over ends 23.

In a similar manner three horizontally corrugated spring leaves 24 maybe arranged m a spring structure as illustrated in Figs. 11 and 12 ofthe drawings, preferably having plain leaf springs or separatmg plates25 therebetween while terminal loops 26 are provided upon the upper leaf24, the oppobeing preferably convexed and providing a compact structureof great strength possessing eat resihency,

T e different forms of corrugated or shown. in each of Figs. 1 to 8inclusive may looped leaf springs may also be utilized as illustrated inFigs. 13 and 14 of the drawings and in which a loop arrangement, suchfor instance, as that illustrated in Fig. 8 is employed with thecorrugations vertically positioned as shown at 28, the two corrugatedleaves being of different lengths and arranged with positioning leafsprings 29 at each edge thereof while the upper spring 29 is providedwith terminal attaching beads 30. t t

.It will be apparent that it is not desired to limit the presentinvention to any particular form of corrugation, loop, or ad-'vantageous bending of the flexible metallic strips in the formation ofthe device nor to limit their employment either singly or in plurality,with the loops arranged horizontally or vertically.

' A serviceable spring structure is arranged having great strength anddurability as well as possessing great resiliency when subjected tostrains both direct as well as torsional,"

such for instance, as those exerted under variable traflic conditionswhen the invention 'is employed as a vehicle spring.

Obviously, the form of corrugated leaf be used in the construction shownin Figs.'

9 to l linclusive. a

What I claim as new is 1., A spring structure comprising a plural-,

ity of resilient corrugated leaves arranged one above another, vplateleaves interposed between the corrugated leaves, and a plate leaf havingmeans whereby the spring may be attached to a supporting structure.

2A spring structure comprising spaced resilient plate leaves and aplurality of corrugated resilient-leaf springs operatively arrangedbetween said plate leaves, with the corrugations thereof arrangedtransversely of the said plates.

In testimony whereof I have affixed my signature in presence of twowitnesses.
